Find the area of the shape below
Answer:
Total Area = 235cm^2
Step-by-step explanation:
Step 1 ) we have our lengths 11 and 20 so we need to separate the into 2 shapes Step 2) Label and draw new shape 20-11 = 9 to show (Shape square 1) = measuring 9 *9 and another (Shape Rectangle 2) = 11* 14 Step 3) Show how you do the multiplication of Square shape 9* 9 = 81cm^2 and Area Rectangle 11 * 14 = 154 cm^2 Total Area = 81+154 = 235cm^2 You can if you like in table multiplication show 11*14 by adding a zero underneath the 14 = 140 +14 = 154 then add and show +81 = 235cm^2 It is always easier to retain a shape if subtracting to get a 2nd shape this way it saves time with subtraction and in my example only needed to subtract 20-11 = 9 then 9*9 = 81cm^2 to retain the 14 *11 = 154cm^2 area for the rectangle
Answer:
Step-by-step explanation
full rectangle area (see figure) - small rectangle area

X^2-bx+16
Answer:
D) 8Step-by-step explanation:
Given trinomial:
x² - bx + 16It has two perfect squares and a variable with negative coefficient.
It can be representing a:
(m - n)² = m² - 2mn + n²If we substitute m with x and n with 4, we'll get 2mn = 2*x*4 = 8x.
This gives us b = 8

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
We can solve the problem in 2 steps, one being Solving and the other being Comprehending. I'll start off with comprehending.
Comprehending
So, we know that 10% of a number is $16. That means that [tex]\frac{1}{10}[/tex] of the number "[tex]x[/tex]" is equal to $16.
A percentage is basically a fraction of something, for example, 25% of a number would be [tex]\frac{1}{4}[/tex] of the same number.
Example:
25% of 10 = [tex]\frac{1}{4} * 10 = 2.5[/tex]
2.5 is 25% of 10 = [tex]2.5 \div \frac{1}{4}=10[/tex]
Now that we know the basics, we can do the real solving.
Solving
To solve, the question, we can first read the problem and make an equation,
"10% of [tex]x[/tex] is 16."
We can then make a equation.
[tex]x(\frac{1}{10})=16[/tex]
[tex]x=16 \div \frac{1}{10} \\x=160[/tex]
After solving, we know that 10% of 160 is equal to 16. We can prove that with the following:
[tex]16*10=160[/tex]
After solving our equation, we can see that the answer is $160.
$16 is 10% of $160.
Cheers!
How do I solve 3 - 4.5 =
Answer:
-1.5
Step-by-step explanation:
3.0 - 4.5 is the same as 3.0 + (-4.5)
in this instance you subtract 3.0 from 4.5 and keep the sign of the larger number, which is 4.5 (you disregard the negative sign)

Vinnie is searching online for airline tickets. Two weeks ago, the cost to fly from Hartford to Denver was $220. Now the cost is $305. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
Answer: 58
Step-by-step explanation:
Answer:
Question 1. 38.6 % 2. 61.4%
Step-by-step explanation:
(New Cost - Old Cost) ÷ old Cost × 100
(305 - 220) ÷ 220 x 100
= 85/220 x 100
= 38.6 %
2. New Cost 305 + 50 = $355
(Now new cost - old cost) ÷ old cost × 100
(355 - 220) ÷ 220 × 100
= 135/220 × 100
61.4%

The house is right now 6years old.
What is linear equation?
" Linear equation is defined as the algebraic expression of one or more variables with highest power equals to one."
According to the question,
'x' represents the present age of house
'y' represents the years left on the mortgage
Given,
y = 24years
As per the condition given linear equation we get,
x + y = 5x
⇒x + 24 = 5x
⇒5x - x = 24
⇒4x = 24
⇒x = 24 / 4
⇒x= 6years old
Hence, The house is right now 6years old.

Round 16.4829 to the nearest hundredth
Answer:
16.48
Step-by-step explanation:
The round off of 16.4829 to the nearest hundredth is 16.48.
What is Rounding off?Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. The supplied number is said to be rounded up when the rounded number is increased, and it is said to be rounded down when the rounded number is dropped.
Given:
16.4829
You rounded to the nearest hundredths place.
The 8 in the hundredths place rounds down to 8, or stays the same,
because the digit to the right in the thousandths place is 2.
and, When the digit to the right is less than 5 we round toward 0.
So, 16.4829 was rounded down toward zero to 16.48.

shen works mowing lawns and babysitting. he earns $9.40 an hour for mowing and $7.80 an hour for babysitting. how much will he earn for 4 hours of mowing and 6 for babysitting?
Answer:
$84.40
Step-by-step explanation:
mowing: $9.40/hour
babysitting: $7.80/hour
4 hours mowing + 6 hours babysitting =
= 4 × $9.40 + 6 × $7.80
= $37.6 + $46.8
= $84.40
Answer:
$84.40
Step-by-step explanation:
$9.40 · 4 + $7.80 · 6 = ?
9.4 · 4 = 37.60
7.8 · 6 = 46.80

What fraction benchmark is .58 closest to?
Answer:
See below:
Step-by-step explanation:
So, since we aren't given any options, there isn't a limit to what it is.
But, assuming you said fraction benchmark it has to be somewhere between 1/2 2/3 3/4 etc.
Now, we can convert the fractions to their equivalent decimal form
1/2 = 0.5
2/3 = 0.66 repeating.
3/4 = 0.75
Now, we can see that 0.58 is 8 units away from 0.66
We can see that it is also 8 units away from 0.5.
But, seeing to that 2/3 is 0.66 with a ton of sixes, it would in theory be away by 8.66 compared to 8 from 0.5
Therefore, we get the closest benchmark is 1/2 (0.5)

Answer:
About 316,955 people
Step-by-step explanation:
The population of this city can be modeled with the formula [tex]P=I\cdot(1.05^t)[/tex], where P represents the current population, I represents the initial population, and t represents the amount of time in years since the start of the model. Plugging in 145,201 for I and (2037-2021)=16 for t, we get:
[tex]P=145201\cdot(1.05)^{16}\approx145201\cdot2.18\approx 316955[/tex]
Initial population=145,201
Total years=2037-2001=36
[tex]\\ \sf\longmapsto S=P\left(1+\dfrac{r}{100}\right)^t[/tex]
[tex]\\ \sf\longmapsto S=145201\left(1+\dfrac{5}{100}\right)^{36}[/tex]
[tex]\\ \sf\longmapsto S=145201\left(\dfrac{105}{100}\right)^{36}[/tex]
[tex]\\ \sf\longmapsto S=145201(1.05)^{16}[/tex]
